Circle O has a radius of 5 centimeters and central angleAOB with a measure of 60°.
1 answer:
The arc length can be found using the formula, ∅ × r, which is: (5π)/3.
<h3>What is the Arc Length?</h3>Arc length = ∅ × r, where ∅ is the central angle in radians, and r is the radius of the circle.
Given the following:
- ∅ = 60° = 60° × π/180 (in radians)
- r = 5 cm
Length of the arc = 60° × π/180 × 5 = (60 × π × 5)/180
Length of the arc = (300π)/180 = (5π)/3

Answer:
- 50.24 inches
Step-by-step explanation:
It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.
To find the circumference of the circle we must know this formula first :
Where
- r is the radius of the circle.
- We'll take the value of π as 3.14
Now substituting the values in the formula :
Therefore,
- The circumference of the circle is 50.24 inches
